North Vancouver’s 1960s Capilano Mall plans for redevelopment
North Shore News
by Brent RichterThe managers of Capilano Mall are planning for redevelopment of the 1960s-era mall.
QuadReal Property Group has begun consultations on exactly what the redevelopment will entail.
“It’s time to consider the future of the site and determine how it can better suit the needs of residents of the City of North Vancouver and the North Shore for the next 50 years,” a statement on the company’s website reads.
There is no timeline for when a rezoning application may go to the City of North Vancouver, but the company has laid out some general expectations following earlier outreach in the summer.
“In June and July 2019, we engaged with 851 North Shore residents and workers. People told us that they love the North Shore’s connection to nature and the outdoors, and that they want accessible public transit and more diverse housing options,” the statement continued.
If the plan advances, it would be the latest of a string of Lower Mainland malls to pursue mixed-used redevelopment, along with Park Royal, Metropolis at Metrotown, Brentwood Town Centre, Lougheed Town Centre, and Oakridge Mall.
Cap Mall originally opened in 1969 and went through expansions and renovations in the ’70s and ’80s. Sears, one of its two anchor tenants, went bankrupt in October 2017.
The mall’s last assessment came in at $123,701,000, with buildings making up just $780,000 of that evaluation of the 653,836-square-foot site.
QuadReal is the property management/development arm of the British Columbia Investment Management Corp., a public employee-owned pension investment firm.
The company is hosting an open house for residents to view the Capilano Mall plans on Thursday, Dec. 5 from 4 to 8 p.m. in the mall’s grand court, next to Starbucks. They have also launched a public feedback survey at capilanomall.com/thinkingcap.
Representatives for Capliano Mall and QuadReal did not return calls to press time.


ROSSTEP 1.2 Documentation
Adam Allevato<EMAIL_ADDRESS>2015-07-31
Intro
Welcome to ROSSTEP! This page will teach you how to use ROSSTEP to create one-click ROS applications.
What ROSSTEP is
- A way of sequentially launching ros nodes, roslaunch files, and other ros-related processes
- A way of preventing ros processes from running until certain conditions are met
- A tool for creating one-click ROS applications
- A possible replacement for roslaunch when less flexibility is needed
- A YAML schema
- Awesome
What ROSSTEP is not
- A flow-control system
- Designed for Windows
- A replacement for the terminal
The ROSSTEP Creator GUI
You should create your ROSSTEP .yaml files using the GUI too, rosstep-creator. All functionality of ROSSTEP is accessible from this gui.
It is possible, but not recommended, to write the ROSSTEP YAML files by hand.
Below is a screenshot of the creator, with three steps already added.
- Action Chooser. Select what type of action you would like to perform. The options are:
- bash - any command that could be run in the terminal
- rosrun - a package name and node name
- roslaunch - a package name and launch file name
- none - no action. Used to make a condition-only step
- Action Text. The text to use when launching the action. For rosrun and roslaunch actions, do not include the text "rosrun" or "roslaunch."
- Required. After a required action has been started, ROSSTEP will kill all program execution if/when that process ends. This is useful for "framework" processes, such as camera data collectors or MoveIt.
- Temporary. This is almost the opposite of Required. When a Temporary step's conditions are met, the action will be forcibly ended. An example of when you may want to do this would be when you want to allow a continuous process to run until it is killed by user input.
- Condition Type. ROSSTEP will not advance to the next step until this condition is met. See the next field for more details.
- Condition Text. The text in this box helps define the condition, as follows:
| Condition Type | Condition Text |
| none | N/A |
| ROS topic | The name of the topic to listen for. The condition will wait until this topic exists on roscore (although this may not imply that messages are being actively published). A leading slash will be automatically added if missing. |
| ROS param | The name of the parameter to wait for. The condition will wait until this parameter exists on roscore. A leading slash will be automatically added if missing. |
| ROS service | The name of the service to wait for. The condition will wait until this service exists on roscore. A leading slash will be automatically added if missing. |
| seconds | How many seconds to wait. Decimal values are accepted. |
| completion | N/A - No text required. Wait for this step's action to complete. This will not work well with Required or Temporary, for obvious reasons. |
| user prompt | The message to display to the user, in a window with an OK button. When OK is pressed, the condition will complete. |
- Move Up Button. Move this step up the stack (towards the beginning of the rosstep program).
- Move Down Button. Move this step down the stack (towards the end of the rosstep program).
- Delete Button. Remove this step from the program.
Use the + button to add new steps to the program.
When you are finished, press the Build button and enter a filename. The creator will generate both a ROSSTEP .yaml file, and an Ubuntu .desktop file, allowing one-click running.
Running your ROSSTEP file
Important: if you move your .yaml file after saving it, you must edit the .desktop file to point to its new location. Moving the yaml file is not recommended. Save it in your package/project folder.
To run, simply double-click the ROSSTEP icon with your program's name.


Every object in a “time” class has its own, distinct, lifetime, which is controlled by the object's reference count. Reference counting follows the usual practice. Contexts which take a share of the “ownership” of an object increase the reference count by 1. When a context relinquishes its share of the ownership of an object, it decreases the reference count by 1.
Each class of time object has a “ref” and an “unref”
method, to be used by those contexts which need to
explicitly increment and decrement the reference count.
For example, the “ref” method for the grammar class is
marpa_g_ref()
and the “unref” method for the grammar class is
marpa_g_unref()
.
Time objects do not have explicit destructors. When the reference count of a time object reaches 0, that time object is destroyed.
Much of the necessary reference counting is performed automatically. The context calling the constructor of a time object does not need to explicitly increase the reference count, because Libmarpa time objects are always created with a reference count of 1.
Child objects “own” their parents, and when a child object is successfully created, the reference count of its parent object is automatically incremented to reflect this. When a child object is destroyed, it automatically decrements the reference count of its parent.
In a typical application, a calling context needs only to remember to “unref” each time object that it creates, once it is finished with that time object. All other reference decrements and increments are taken care of automatically. The typical application never needs to explicitly call one of the “ref” methods.
More complex applications may find it convenient to have one or more contexts share ownership of objects created in another context. These more complex situations are the only cases in which the “ref” methods will be needed.

Wow. This was my first experience with Morning Glory seeds, and I can give a brief description of how well it worked. I prepared this stuff by grinding it in a pepper mill, mixing the crushed seeds with hot water, and letting sit for 10 hours. Then, I took a cooking metal strainer and got the liquid out of the mush. I used 5 packs of Heavenly Blue variety.
9:30 - Ate a light breakfast, some cereal
10:00 - Took the liquid (mixed with soda)
10:30 - Mild lightness was felt, nausea was coming on
10:45 - Had some marijuana smokes with a sober friend. I would like to recommend this for ANYONE who has this available. This got rid of the nausea feeling within minutes, and for the rest of the trip.
After that, the effects were starting to come on, slowly. I recall looking up at a ceiling light and feeling almost a burning sensation in the eyes (it made my eyes watery) just looking at natural sunlight. I felt light in the mind. Soon, I realized what was happening, my nostrils seemed to be closing. Breathing was becoming increasingly difficult, and for the rest of the trip, my nose was pretty much closed.
I recall feelings of happiness, and motion seemed much different when riding in a car (bumps and dips caused me to laugh). Listening to some techno beats would cause me to laugh histerically, my friend told me afterwards (i do vaugely remember this happening). Music felt as if it were crawling inside of you, and since it was not mellow (it was techno) everything felt 'uneven' and not very smooth. Food tasted entirely different (I recall eating some candy, and telling my friend that it tasted like rocks, and it took me like 10 mins or so to eat like 3 skittles!)
All I can say is that it was fun, and I felt the universal feeling sometimes associated with MG. Next time maybe i'll up to 6 packs or so.

This package provides a GUI for collecting online data in an emotion experiment.The process of the emotion experiment is as follows.
The experiment consists of several trials.
- At the begining of each trial, there is a 10-second countdown in the
center of the screen to capture each subject’s attention and to serve as an indicator of the next clip.
- After the countdown is complete, movie clips that include different
emotional states are presented on the full screen. While the movie clips are palying, we record the signal of the subjects.
- After each trials ends, a SAM form will appear to evaluate the emotion
when the subject is watching clips.
Both of the singnal and emotion ground truth label will be saved in thehard disk.
In this package, we collected EEG and facial expression data as example.
Here is some instruction of hwo to use this framework.
- If you just want to collect EEG and facial expression dataset. just run
start_GUI.py using commond ‘python start_GUI.py’ and it will start the experiment.
- If you want to use it in your own code. You can follow the example
presented in ‘start_GUI.py’. You first create the ‘DataCollection’ object and then add some ‘recorder’ to it. Finally, you call the method start(). As for the ‘recorder’, please see 3.
- If you want to record different singnal, for example, ECG, you will have
to create a new class who inheirs ‘AbstractRecorder’ in ‘util’. Please see the class document in ‘AbstractRecorder’, where it will give you more detail about how to create a recorder.
Here it will show you how this framework works.
- When you call start() method in the DataCollection class. It all begins.
- An personal information form comes out. It requires the test subject
for their personal information and those information will be saved as well.
- When the ‘start Testing’ button is clicked, one trial starts.
- In the beginning of each trials, a 10-s countdown page appears.
- After the countdown, the corresponding video is presented. In the mean
time, the recorder start recording the data.
- When the video is over, the recorder stops recording and a page with a SAM
form appears. This page requires the subject repoert their emotion status. After clicking ‘Submit’ button, if there is still some trial left, return to 4, else go to 7.
- A finish page will appear and 3-s countdown will start. When the countdown
is over, the GUI will close and the program will quit.
This script gives an example of how to use this data collection framework.

PHENOMENA (1984)
A film review by Mike Watson Copyright 1997 Mike Watson
RATING: 4 out of 5
The "Italian Hitchcock" and acknowledged master of the giallo murder-mystery Dario Argento again offers us a fascinating turn on the formula in PHENEOMENA.
This time the twist comes in the form of Jennifer Corvino (Jennifer Connelly), a bright teenager with gift for telepathically communicating with insects. Sent to a girls boarding school in Switzerland, she soon learns of a series of bizarre disappearances and at least one murder that has the school's population terrified. A chance meeting with a brilliant entomologist (Donald Pleasance) leads the two of them to team up and solve the mystery with the aid of her remarkable gift.
PHENOMENA is an imaginative, original thriller. Writer/director Argento creates several sequences of surreal, haunting beauty here, including a masterfully shot sleepwalking episode and a striking scene when a swarm of flying insects descends on the school at Jennifer's beckoning. The plot takes some wonderfully bizarre turns and the killer's identity is genuinely shocking and surprising.
The director took a big gamble with a soundtrack that mixes elements as diverse as heavy metal band Iron Maiden, ex-Rolling Stone Bill Wyman, and Argento's favourite Gothic/electronic outfit Goblin. But it gels surprisingly well. The film's opening music reccurs several times, an eerie and evocative score that perfectly sets the overall tone.
Argento fans beware: the film was released outside Europe in a terribly butchered form re-titled as CREEPERS. This deleted nearly half an hour of footage, mainly of key dialogue scenes.

There will probably be a function to create a map in one run in the next major version of {DatawRappr}. In the meantime, I wrote this tutorial:
There are three map types in Datawrapper: locator, symbol and choropleth. I’m trying to explain in short, how you can use DatawRappr to create a map programmatically for symbols and choropleths. And as an add-on: How to create a tooltip using {DatawRappr}.
Why exclude Locator-maps? They are a little tricky and probably not so heavily automated compared to choropleths and symbols. That’s why I decided place them a little lower on my priority list and keep them out here. There is a tutorial on Locator-maps with the API by Datawrapper using curl
.
The basic steps are always the same:
map
.If you want to update the data, you will only need steps 2 and 4.
You can use this code to create a new chart and save the chart to your current environment. You don’t have to save it. You will just need the chart-id later.
new_choropleth_chart <- dw_create_chart(
title = "This is a automated choropleth map",
type = "d3-maps-choropleth"
)
#> New chart's id: E4ytb
We will now upload some data to our newly created map. Beforehand, we have to decide on an basemap and a key that maps the data to the chart.
Datawrapper provides an API-endpoint with their basemaps, which you might curl
curl --request GET \
--url https://api.datawrapper.de/plugin/basemaps
Or you can use the built-in dataframe in DatawRappr:
head(dw_basemaps)
#> # A tibble: 6 × 6
#> id level slug value label description
#> <chr> <chr> <chr> <chr> <chr> <chr>
#> 1 world-2019 World world DW_NAME Name The three-letter …
#> 2 world-2019 World world NAME_SHORT Name (short) The three-letter …
#> 3 world-2019 World world DW_STATE_CODE ISO-Code The written name …
#> 4 world-2019 World world GERMAN_NAME_NEW Name (German) The written name …
#> 5 world-2019 World world GERMAN_NAME Name old (German) The written name …
#> 6 africa-2020 Africa africa DW_NAME Name The three-letter …
First, you have to decide, which map to use. It is identified by the id
-column.
You can use dplyr’s View()
to get an interactive table. Or you might want to filter using grepl()
dw_basemaps %>%
filter(grepl("us-nyc", id))
#> # A tibble: 12 × 6
#> id level slug value label description
#> <chr> <chr> <chr> <chr> <chr> <chr>
#> 1 us-nyc-boros USA » New … usa-new-yo… BoroN… Boroug… "Name of th…
#> 2 us-nyc-censustracts USA » New … usa-new-yo… BoroC… BoroCT… ""
#> 3 us-nyc-censustracts USA » New … usa-new-yo… geoid GEOID … ""
#> 4 us-nyc-citycouncils USA » New … usa-new-yo… CounD… Counci… ""
#> 5 us-nyc-communitydistricts USA » New … usa-new-yo… BoroCD Boro C… ""
#> 6 us-nyc-hoods USA » New … usa-new-yo… NTANa… NTA Na… ""
#> 7 us-nyc-hoods USA » New … usa-new-yo… NTACo… NTA Co… ""
#> 8 us-nyc-policeprecincts USA » New … usa-new-yo… Preci… Precin… ""

#> 11 us-nyc-uhf USA » New … usa-new-yo… uhf_n… Name "Name of th…
#> 12 us-nyc-zipcodes USA » New … usa-new-yo… ZIPCO… ZIP co… ""
In a second step, you have to choose a key for the map, which is identified in value
. label
and description
provide some more details about it.
The key is the variable that binds the data to the map.
dw_basemaps %>%
filter(grepl("germany-nuts3", id))
#> # A tibble: 2 × 6
#> id level slug value label description
#> <chr> <chr> <chr> <chr> <chr> <chr>
#> 1 germany-nuts3 Germany » NUTS3 (2016) germany-nuts3-2016 NUTS_NAME Name The writte…
#> 2 germany-nuts3 Germany » NUTS3 (2016) germany-nuts3-2016 NUTS_ID Code code / desc
In this example the basemap germany-nuts3
offers two key-options: NUTS_ID
and NUTS_NAME
. If you already have one of these options in your dataset, select the right one.
Otherwise, you will have to wrangle the data anyway.
Getting Country IDs
You can easily transform country names in various formats and languages with the {countrycode}-package. In most cases you won’t need a manual translation table. The package is available via CRAN or Github.
After installation, simply add a column with something like countrycode::countrycode(sourcevar = SOURCE VARIABLE, origin = "country.name.de", destination = "iso3c")
to your dataframe.
Just in case you need it: You can retrieve the expected keys for a basemap by calling this API-endpoint. Simply enter the id
of the basemap and the value
of the key:
curl --request GET \
--url https://api.datawrapper.de/plugin/basemaps/ID/VALUE
you could also use the {jsonlite}-package for this task:
library(jsonlite)
r <- fromJSON("https://api.datawrapper.de/plugin/basemaps/germany-states/name")
r$data$values
#> [1] "Nordrhein-Westfalen" "Baden-Württemberg" "Hessen"
#> [4] "Bremen" "Niedersachsen" "Thüringen"
#> [7] "Hamburg" "Schleswig-Holstein" "Rheinland-Pfalz"
#> [10] "Saarland" "Bayern" "Berlin"
#> [13] "Sachsen-Anhalt" "Sachsen" "Brandenburg"
#> [16] "Mecklenburg-Vorpommern"
We are using a simple dataset for German States here as an example: It contains the share of foreign population per German federal state (source: Federal Statistical Office Germany (Destatis)).
df_foreign_pop <- read.csv("data/foreign_pop.csv", stringsAsFactors = FALSE)
str(df_foreign_pop)
#> 'data.frame': 16 obs. of 2 variables:
#> $ state : chr "Baden-Württemberg" "Bayern" "Berlin" "Brandenburg" ...
#> $ share_foreign_population: num 15.5 13.2 18.5 4.7 18.1 16.4 16.2 4.5 9.4 13.3 ...
You can simply upload the data as you would do with any other {DatawRappr}-chart.
dw_data_to_chart(df_foreign_pop, chart_id = new_choropleth_chart)
#> Warning in if (format == "csv") {: Bedingung hat Länge > 1 und nur das erste

The metadata of a chart gives us the full flexibility to change what we want to change. In this case, we have to set the axes. A chart in Datawrapper returned as a JSON-Object, which contains differents sublevels. One of those is called metadata and contains the relevant keys:
"metadata": {
"axes": {
"keys": "KEY FROM DATA",
"values": "VALUE FROM DATA"
},
"visualize": {
"basemap": "ID of the basemap",
"map-key-attr": "VALUE of the map key"
}
}
In our example from above, we are using the names of the German federal states as the IDs. We will therefore use the basemap germany-states with the value name. name consists of the keys that are already present in our dataset in the state-column. So we don’t need any transformation here. We just need to tell Datawrapper which column to use.
dw_edit_chart(new_choropleth_chart,
axes = list(
keys = "state",
values = "share_foreign_population"
),
visualize = list(
basemap = "germany-states",
"map-key-attr" = "name"
)
)
#> Chart E4ytb succesfully updated.
At that point, you might want to switch to Datawrapper’s UI to make the final adjustments to the legend before publishing. But: You could do them via dw_edit_chart
as well. It’s probably just not that much fun.
This is probably the easiest part:
dw_publish_chart(new_choropleth_chart)
#> Chart E4ytb published!
#> ### Responsive iFrame-code: ###
#>
#>
#> ### Chart-URL:###
#> https://datawrapper.dwcdn.net/E4ytb/1/
A symbol map maps a certain value to a geographic location. We will use predefined coordinates here. Datawrapper’s user interface allows geocoding of adresses.
The workflow is pretty similar to the choropleth map. The main difference: We will use Latitude and Longitude coordinates, instead of the key.
You can use this code to create a new chart and save the chart to your current environment. You don’t have to save it. You will just need the chart-id later.
new_symbol_chart <- dw_create_chart(
title = "This is a automated symbol map",
type = "d3-maps-symbols"
)
#> New chart's id: PGgcj
We will now upload some data to our newly created map. Beforehand, we have to decide on an basemap.
Datawrapper provides an API-endpoint with their basemaps, which you might curl
curl --request GET \
--url https://api.datawrapper.de/plugin/basemaps
Or you can use the built-in dataframe in {DatawRappr}:
head(dw_basemaps)
#> # A tibble: 6 × 6
#> id level slug value label description
#> <chr> <chr> <chr> <chr> <chr> <chr>
#> 1 world-2019 World world DW_NAME Name The three-letter …
#> 2 world-2019 World world NAME_SHORT Name (short) The three-letter …
#> 3 world-2019 World world DW_STATE_CODE ISO-Code The written name …
#> 4 world-2019 World world GERMAN_NAME_NEW Name (German) The written name …
#> 5 world-2019 World world GERMAN_NAME Name old (German) The written name …
#> 6 africa-2020 Africa africa DW_NAME Name The three-letter …
First, you have to decide, which map to use. It is identified by the id
-column.
You can use dplyr’s View()
to get an interactive table. Or you might want to filter using grepl()
dw_basemaps %>%
filter(grepl("us-nyc", id))
#> # A tibble: 12 × 6
#> id level slug value label description
#> <chr> <chr> <chr> <chr> <chr> <chr>

We are using a simple dataset for German States here as an example: It contains the share of foreign population per German federal state (source: Federal Statistical Office Germany (Destatis)).
df_foreign_pop_symbol <- read.csv("data/foreign_pop_symbol.csv", stringsAsFactors = FALSE)
str(df_foreign_pop_symbol)
#> 'data.frame': 16 obs. of 4 variables:
#> $ Lat : num 48.6 48.9 52.5 52.8 53.1 ...
#> $ Lon : num 9.19 11.4 13.39 13.25 8.81 ...
#> $ name : chr "Baden-Württemberg" "Bayern" "Berlin" "Brandenburg" ...
#> $ share_foreign_population: num 15.5 13.2 18.5 4.7 18.1 16.4 16.2 4.5 9.4 13.3 ...
The data is already geocoded into the Lat and Lon-columns. They are required for the symbol map.
Geocoding Adresses
There are loads of resources on how to geocode places with R. For example, you might want to check out the {ggmap}-package. Unfortunately geocoding with Google does require an API-Key.
For open alternatives you might have a look at hrbrmstr’s {nominatim} or the geocode_OSM()
-function in {tmaptools}.
With Lat and Lon-columns set, you can simply upload the data as you would do with any other {DatawRappr}-chart.
dw_data_to_chart(df_foreign_pop_symbol, chart_id = new_symbol_chart)
#> Warning in if (format == "csv") {: Bedingung hat Länge > 1 und nur das erste
#> Element wird benutzt
#> Data in PGgcj successfully updated.

In our example from above, we are using the names of the German federal states as the IDs. We will therefore use the basemap germany-states. We just need to tell Datawrapper which basemap and columns to use for the mapping. Further options in axes
would be:
area
: for the area/size of the symbolvalue
: for the color of the symbol
dw_edit_chart(new_symbol_chart,

Including a tooltip is a task that is not only useful for maps, but also for scatterplots. The way to change them via tha API are pretty easy. Just use the visualize
-argument in dw_edit_chart()
and add a list which includes another list called tooltip
.
tooltip has three different keys:
body
: which is the body text of the tooltip. Add double brackets ton include a variable: {{ variable }}
.title
: is the title of the tooltip. It may also contain a variable with double brackets.fields
: is a list that contains the mapping between the chart data and the variables in the tooltips. You have to include each variable here that is used in the tooltip double brackets in the format: "variable in tooltip" = "variable in data"
. You may (although it makes things more complicated) map variables to different names, as shown below where "name" = "b"
.
dw_edit_chart(CHART_ID, visualize = list(
tooltip = list(
body = "{{ name }} has value {{ a }}.",
title = "{{ name }}",
fields = list(
"name" = "b",
"a" = "a"
)
)))


Who will be responsible for project finances in your organisation?
We will ask this person to:
If you add a new team member this section will remain in a pending state until they have accepted. Once the team member has created their account you can assign them the role of finance contact.
This will make [name] your finance contact for the project.
[Name] has been invited to create an account. This must be completed before they can be assigned as your finance contact.


| Methods' Details |
waitForCompletion
- Description
- waits for the completion of any previous calls to
XOutputStream::writeBytes,
and reports potentially pending errors.
Calling this method is potentially expensive (even if the associated
XOutputStream represents a local
file not accessed via NFS, for example). This method has a similar
description to
XOutputStream::flush.
However, where the semantics of flush are rather vague,
waitForCompletion has very specific semantics—it just
blocks long enough so that any errors encountered during previous calls
to XOutputStream::writeBytes
can reliably be reported. It specificially does not guarantee that any
data have savely been stored on a stable physical medium, like a hard
disk (and it is completely unspecified whether flush should
give this guarantee).
- Throws
- com::sun::star::io::IOException
if any previous call to XOutputStream::writeBytes encountered
such an error, but has not yet reported it (in cases where
writeBytes operates asynchronously).

Email Verification
Introduction
Many web applications require users to verify their email addresses before using the application. Rather than forcing you to re-implement this feature by hand for each application you create, Laravel provides convenient built-in services for sending and verifying email verification requests.
{tip} Want to get started fast? Install one of the Laravel application starter kits in a fresh Laravel application. The starter kits will take care of scaffolding your entire authentication system, including email verification support.
Model Preparation
Before getting started, verify that your App\Models\User
model implements the Illuminate\Contracts\Auth\MustVerifyEmail
contract:
<?php
namespace App\Models;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
class User extends Authenticatable implements MustVerifyEmail
{
use Notifiable;
// ...
}
Once this interface has been added to your model, newly registered users will automatically be sent an email containing an email verification link. As you can see by examining your application's App\Providers\EventServiceProvider
, Laravel already contains a SendEmailVerificationNotification
listener that is attached to the Illuminate\Auth\Events\Registered
event. This event listener will send the email verification link to the user.
If you are manually implementing registration within your application instead of using a starter kit, you should ensure that you are dispatching the Illuminate\Auth\Events\Registered
event after a user's registration is successful:
use Illuminate\Auth\Events\Registered;
event(new Registered($user));
Database Preparation
Next, your user
table must contain an email_verified_at
column to store the date and time that the user's email address was verified. By default, the users
table migration included with the Laravel framework already includes this column. So, all you need to do is run your database migrations:
php artisan migrate
Routing
To properly implement email verification, three routes will need to be defined. First, a route will be needed to display a notice to the user that they should click the email verification link in the verification email that Laravel sent them after registration.
Second, a route will be needed to handle requests generated when the user clicks the email verification link in the email.
Third, a route will be needed to resend a verification link if the user accidentally loses the first verification link.
The Email Verification Notice
As mentioned previously, a route should be defined that will return a view instructing the user to click the email verification link that was emailed to them by Laravel after registration. This view will be displayed to users when they try to access other parts of the application without verifying their email address first. Remember, the link is automatically emailed to the user as long as your App\Models\User
model implements the MustVerifyEmail
interface:
Route::get('/email/verify', function () {
return view('auth.verify-email');
})->middleware('auth')->name('verification.notice');
The route that returns the email verification notice should be named verification.notice
. It is important that the route be assigned this exact name since the verified
middleware included with Laravel will automatically redirect to this route name if a user has not verified their email address.
{tip} When manually implementing email verification, you are required to define the contents of the verification notice view yourself. If you would like scaffolding that includes all necessary authentication and verification views, check out the Laravel application starter kits.
The Email Verification Handler
Next, we need to define a route that will handle requests generated when the user clicks the email verification link that was emailed to them. This route should be named verification.verify
and be assigned the auth
and signed
middlewares:
use Illuminate\Foundation\Auth\EmailVerificationRequest;
use Illuminate\Http\Request;
Route::get('/email/verify/{id}/{hash}', function (EmailVerificationRequest $request) {
$request->fulfill();
return redirect('/home');
})->middleware(['auth', 'signed'])->name('verification.verify');
Before moving on, let's take a closer look at this route. First, you'll notice we are using an EmailVerificationRequest
request type instead of the typical Illuminate\Http\Request
instance. The EmailVerificationRequest
is a form request that is included with Laravel. This request will automatically take care of validating the request's id
and hash
parameters.
Next, we can proceed directly to calling the fulfill
method on the request. This method will call the markEmailAsVerified
method on the authenticated user and dispatch the Illuminate\Auth\Events\Verified
event. The markEmailAsVerified
method is available to the default App\Models\User
model via the Illuminate\Foundation\Auth\User
base class. Once the user's email address has been verified, you may redirect them wherever you wish.
Resending The Verification Email
Sometimes a user may misplace or accidentally delete the email address verification email. To accommodate this, you may wish to define a route to allow the user to request that the verification email be resent. You may then make a request to this route by placing a simple form submission button within your verification notice view:
use Illuminate\Http\Request;
Route::post('/email/verification-notification', function (Request $request) {
$request->user()->sendEmailVerificationNotification();
return back()->with('message', 'Verification link sent!');
})->middleware(['auth', 'throttle:6,1'])->name('verification.send');
Protecting Routes
Route middleware may be used to only allow verified users to access a given route. Laravel ships with a verified
middleware, which references the Illuminate\Auth\Middleware\EnsureEmailIsVerified
class. Since this middleware is already registered in your application's HTTP kernel, all you need to do is attach the middleware to a route definition:
Route::get('/profile', function () {
// Only verified users may access this route...
})->middleware('verified');
If an unverified user attempts to access a route that has been assigned this middleware, they will automatically be redirected to the verification.notice
named route.
Customization
Verification Email Customization
Although the default email verification notification should satisfy the requirements of most applications, Laravel allows you to customize how the email verification mail message is constructed.
To get started, pass a closure to the toMailUsing
method provided by the Illuminate\Auth\Notifications\VerifyEmail
notification. The closure will receive the notifiable model instance that is receiving the notification as well as the signed email verification URL that the user must visit to verify their email address. The closure should return an instance of Illuminate\Notifications\Messages\MailMessage
. Typically, you should call the toMailUsing
method from the boot
method of your application's App\Providers\AuthServiceProvider
class:
use Illuminate\Auth\Notifications\VerifyEmail;
use Illuminate\Notifications\Messages\MailMessage;
/**
* Register any authentication / authorization services.
*
* @return void
*/
public function boot()
{
// ...
VerifyEmail::toMailUsing(function ($notifiable, $url) {
return (new MailMessage)
->subject('Verify Email Address')
->line('Click the button below to verify your email address.')
->action('Verify Email Address', $url)
});
}
{tip} To learn more about mail notifications, please consult the mail notification documentation.
Events
When using the Laravel application starter kits, Laravel dispatches events during the email verification process. If you are manually handling email verification for your application, you may wish to manually dispatch these events after verification is completed. You may attach listeners to these events in your application's EventServiceProvider
:
/**
* The event listener mappings for the application.
*
* @var array
*/
protected $listen = [
'Illuminate\Auth\Events\Verified' => [
'App\Listeners\LogVerifiedUser',
],
];

A valid MPI implementation guarantees certain general properties of point-to-point communication, which are described in this section.
Order Messages are non-overtaking: If a sender sends two messages in succession to the same destination, and both match the same receive, then this operation cannot receive the second message if the first one is still pending. If a receiver posts two receives in succession, and both match the same message, then the second receive operation cannot be satisfied by this message, if the first one is still pending. This requirement facilitates matching of sends to receives. It guarantees that message-passing code is deterministic, if processes are single-threaded and the wildcard MPI_ANY_SOURCE is not used in receives. (Some of the calls described later, such as MPI_CANCEL or MPI_WAITANY, are additional sources of nondeterminism.)
If a process has a single thread of execution, then any two communications executed by this process are ordered. On the other hand, if the process is multi-threaded, then the semantics of thread execution may not define a relative order between two send operations executed by two distinct threads. The operations are logically concurrent, even if one physically precedes the other. In such a case, the two messages sent can be received in any order. Similarly, if two receive operations that are logically concurrent receive two successively sent messages, then the two messages can match the two receives in either order.
Example
An example of non-overtaking messages.
CALL MPI_COMM_RANK(comm, rank, ierr) IF (rank.EQ.0) THEN CALL MPI_BSEND(buf1, count, MPI_REAL, 1, tag, comm, ierr) CALL MPI_BSEND(buf2, count, MPI_REAL, 1, tag, comm, ierr) ELSE ! rank.EQ.1 CALL MPI_RECV(buf1, count, MPI_REAL, 0, MPI_ANY_TAG, comm, status, ierr) CALL MPI_RECV(buf2, count, MPI_REAL, 0, tag, comm, status, ierr) END IFThe message sent by the first send must be received by the first receive, and the message sent by the second send must be received by the second receive.
Progress If a pair of matching send and receives have been initiated on two processes, then at least one of these two operations will complete, independently of other actions in the system: the send operation will complete, unless the receive is satisfied by another message, and completes; the receive operation will complete, unless the message sent is consumed by another matching receive that was posted at the same destination process.
Example
An example of two, intertwined matching pairs.
CALL MPI_COMM_RANK(comm, rank, ierr) IF (rank.EQ.0) THEN CALL MPI_BSEND(buf1, count, MPI_REAL, 1, tag1, comm, ierr) CALL MPI_SSEND(buf2, count, MPI_REAL, 1, tag2, comm, ierr) ELSE ! rank.EQ.1 CALL MPI_RECV(buf1, count, MPI_REAL, 0, tag2, comm, status, ierr) CALL MPI_RECV(buf2, count, MPI_REAL, 0, tag1, comm, status, ierr) END IFBoth processes invoke their first communication call. Since the first send of process zero uses the buffered mode, it must complete, irrespective of the state of process one. Since no matching receive is posted, the message will be copied into buffer space. (If insufficient buffer space is available, then the program will fail.) The second send is then invoked. At that point, a matching pair of send and receive operation is enabled, and both operations must complete. Process one next invokes its second receive call, which will be satisfied by the buffered message. Note that process one received the messages in the reverse order they were sent.
Fairness MPI makes no guarantee of fairness in the handling of communication. Suppose that a send is posted. Then it is possible that the destination process repeatedly posts a receive that matches this send, yet the message is never received, because it is each time overtaken by another message, sent from another source. Similarly, suppose that a receive was posted by a multi-threaded process. Then it is possible that messages that match this receive are repeatedly received, yet the receive is never satisfied, because it is overtaken by other receives posted at this node (by other executing threads). It is the programmer's responsibility to prevent starvation in such situations.
Resource limitations Any pending communication operation consumes system resources that are limited. Errors may occur when lack of resources prevent the execution of an MPI call. A quality implementation will use a (small) fixed amount of resources for each pending send in the ready or synchronous mode and for each pending receive. However, buffer space may be consumed to store messages sent in standard mode, and must be consumed to store messages sent in buffered mode, when no matching receive is available. The amount of space available for buffering will be much smaller than program data memory on many systems. Then, it will be easy to write programs that overrun available buffer space.
MPI allows the user to provide buffer memory for messages sent in the buffered mode. Furthermore, MPI specifies a detailed operational model for the use of this buffer. An MPI implementation is required to do no worse than implied by this model. This allows users to avoid buffer overflows when they use buffered sends. Buffer allocation and use is described in Section Buffer allocation and usage .
A buffered send operation that cannot complete because of a lack of buffer space is erroneous. When such a situation is detected, an error is signalled that may cause the program to terminate abnormally. On the other hand, a standard send operation that cannot complete because of lack of buffer space will merely block, waiting for buffer space to become available or for a matching receive to be posted. This behavior is preferable in many situations. Consider a situation where a producer repeatedly produces new values and sends them to a consumer. Assume that the producer produces new values faster than the consumer can consume them. If buffered sends are used, then a buffer overflow will result. Additional synchronization has to be added to the program so as to prevent this from occurring. If standard sends are used, then the producer will be automatically throttled, as its send operations will block when buffer space is unavailable.
In some situations, a lack of buffer space leads to deadlock situations. This is illustrated by the examples below.
Example
An exchange of messages.
CALL MPI_COMM_RANK(comm, rank, ierr) IF (rank.EQ.0) THEN CALL MPI_SEND(sendbuf, count, MPI_REAL, 1, tag, comm, ierr) CALL MPI_RECV(recvbuf, count, MPI_REAL, 1, tag, comm, status, ierr) ELSE ! rank.EQ.1 CALL MPI_RECV(recvbuf, count, MPI_REAL, 0, tag, comm, status, ierr) CALL MPI_SEND(sendbuf, count, MPI_REAL, 0, tag, comm, ierr) END IFThis program will succeed even if no buffer space for data is available. The standard send operation can be replaced, in this example, with a synchronous send.
Example
An attempt to exchange messages.
CALL MPI_COMM_RANK(comm, rank, ierr) IF (rank.EQ.0) THEN CALL MPI_RECV(recvbuf, count, MPI_REAL, 1, tag, comm, status, ierr) CALL MPI_SEND(sendbuf, count, MPI_REAL, 1, tag, comm, ierr) ELSE ! rank.EQ.1 CALL MPI_RECV(recvbuf, count, MPI_REAL, 0, tag, comm, status, ierr) CALL MPI_SEND(sendbuf, count, MPI_REAL, 0, tag, comm, ierr) END IFThe receive operation of the first process must complete before its send, and can complete only if the matching send of the second processor is executed. The receive operation of the second process must complete before its send and can complete only if the matching send of the first process is executed. This program will always deadlock. The same holds for any other send mode.
Example
An exchange that relies on buffering.
CALL MPI_COMM_RANK(comm, rank, ierr) IF (rank.EQ.0) THEN CALL MPI_SEND(sendbuf, count, MPI_REAL, 1, tag, comm, ierr) CALL MPI_RECV(recvbuf, count, MPI_REAL, 1, tag, comm, status, ierr) ELSE ! rank.EQ.1 CALL MPI_SEND(sendbuf, count, MPI_REAL, 0, tag, comm, ierr) CALL MPI_RECV(recvbuf, count, MPI_REAL, 0, tag, comm, status, ierr) END IFThe message sent by each process has to be copied out before the send operation returns and the receive operation starts. For the program to complete, it is necessary that at least one of the two messages sent be buffered. Thus, this program can succeed only if the communication system can buffer at least count words of data.
[] Advice to users.
When standard send operations are used, then a deadlock situation may occur where both processes are blocked because buffer space is not available. The same will certainly happen, if the synchronous mode is used. If the buffered mode is used, and not enough buffer space is available, then the program will not complete either. However, rather than a deadlock situation, we shall have a buffer overflow error.
A program is ``safe'' if no message buffering is required for the program to complete. One can replace all sends in such program with synchronous sends, and the program will still run correctly. This conservative programming style provides the best portability, since program completion does not depend on the amount of buffer space available or in the communication protocol used.
Many programmers prefer to have more leeway and be able to use the ``unsafe'' programming style shown in example Semantics of point-to-point communication . In such cases, the use of standard sends is likely to provide the best compromise between performance and robustness: quality implementations will provide sufficient buffering so that ``common practice'' programs will not deadlock. The buffered send mode can be used for programs that require more buffering, or in situations where the programmer wants more control. This mode might also be used for debugging purposes, as buffer overflow conditions are easier to diagnose than deadlock conditions.
Nonblocking message-passing operations, as described in
Section Nonblocking communication
, can be used to avoid the need for buffering
outgoing messages. This prevents deadlocks due to lack of buffer space, and
improves performance, by allowing overlap of computation and communication,
and avoiding the overheads of allocating buffers and copying messages into
buffers.

Sometimes, navigate through HTML parse tree may not get you what you need. For instance, you have some information inside a javascript function. You don't really want the whole bloc. All you care about is API key.
Or you got multiple titles. You only care about the numbers inside these titles. You are unable to use array slicing with indices because numbers don't appear in fixed positions. Those numbers can even be negative.
Helpless, right? Not if you know regular expression! We will call it regex in the following context. Think of regex as another simple language as HTML. In Python, there is a built-in library called re. There are a couple of functions inside this module. But for web scraping, re.findall and re.search are commonly used. re.findall returns a list of all the matched words and re.search returns a regex object. We simply apply attribute re.search('','').group() to concatenate the text together.
As for the regex itself, there are a few useful tips. (?<=) and (?=) are my favorite pair. They are called look-ahead and look-behind. If the content you are looking for is always behind a comma and before a question mark. You can simply do
(?<=\,)\S*(?=\?)
Punctuation marks have special meanings in regex. If you need to specify comma instead of special meanings, you always remember to put a slash before it. \S* refer to all the non-whitespace characters. Characters have no special meanings in regex. But when you put a slash before characters, all of sudden they have special meanings, quite the opposite to punctuation marks.
The full table of my useful tips is here.
| Syntax | Meaning |
|---|---|
| \d* | All the numbers. If we remove asterisk mark, w... |
| \w* | All the characters, numbers and underscore marks |
| \S* | All the non-whitespace characters |
| -?\d*\,?\d* | All the numbers, potential negative signs and ... |
| \d{4} | 4 digits |
| ^Tori | Anything starts with Tori |
| Black$ | Anything ends with Black |
| [a-z0-9] | Anything involves lower case characters or digits |
| [^A-Z] | Anything except upper case characters |
| (?<=\,)\S*(?=\?) | Anything behind a comma and before a question ... |
You can check w3schools for more details on regex syntax.
In this chapter, the example is to navigate through a JSON file by regex (way faster than parsed as a pandas dataframe). Recalled from the previous chapter, JSON file is sort of dictionaries inside dictionaries. Normally we access the value by multiple keys. If you think of JSON file as a tree ADT, we need to know every node (key) from root to parent to go to the child node (value). Now we convert the whole structure to string and search for certain patterns via regex. With look-ahead and look-behind pair, knowing a parent node is fairly sufficient to get the value. Don't believe me? Feel free to take a look at SHFE for coding details.

My research and teaching focus on software quality assurance. My research has a particular emphasis on “black-box” components - software units that lack documentation and cannot be scrutinised internally. I specialise in applying Machine Learning and other data analysis algorithms to the specific activities of testing, reverse-engineering, and safety-case assessment.
I studied my Ph.D. (2002-2005) at the University of Strathclyde on the use of static analysis to support software inspections. I subsequently spent five years (2005-2010) as a postdoc at the University of Sheffield, working on state machine inference and software testing (an area in which I am still active). This was followed by 8 years as a Lecturer then Senior Lecturer / Associate Professor at the Department of Informatics at the University of Leicester. I took up my current position as a Senior Lecturer at the University of Sheffield in 2018.
Within my department I am the Director of Equality, Diversity and Inclusivity. Most of my involvement over the past decade has revolved around initiatives to encourage more women to join (and stay in) our discipline. Most of this takes place through the development and management of Athena SWAN action plans. We are currently however also actively working towards action plans for Race Equality, along with initiatives to better support our neurodiverse students and staff. I am always eager to discuss ideas or potential joint initiatives in this area.
